The company owns half of SpaceX competitor United Launch Alliance in addition to a number of major defense franchises, including the F-35 Joint Strike Fighter. In 2020, Lockheed generated $65 billion in revenue. SpaceX is part of a generation of new, private space companies focused on pushing humanity's boundaries and has had some success as a government contractor, including working with NASA to deliver astronauts to the International Space Station. Some of its more ambitious efforts, like attempting to develop a spaceship capable of delivering humans to Mars, are in earlier stages. The company's massive Starship prototype rockets have experienced a series of high-profile explosions in test flights, though it is still an experimental program. It is also working to launch hundreds of small satellites into space in order to operate its Starlink broadband internet service. 10 stocks we like better than Lockheed MartinWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
